Embodiment 1

[0038] Embodiment 1 Microscale Thermophoresis (MicroscaleThermophoresis, MST) measures the direct binding of Letermovir to the SARS-CoV-2 novel coronavirus S protein RBD region

[0039] 1. Principle

[0040] This technology is based on the thermophoretic phenomenon of biomolecules. MST uses infrared lasers for local heating to cause directional movement of molecules, and then analyzes the directional movement of particles in microscopic temperature gradients through fluorescence. Changes in the size, charge and hydration layer of biomolecules due to binding can be detected.

[0041] 2. Application

[0042] (1) The binding process of the single-chain antibody to the human antigen protein;

[0043] (2) The interaction between small molecule compounds and model proteins;

[0044] (3) Interaction between in vitro synthesized protein and conjugate molecule;

[0045] (4) The itinerary of the three-dimensional helical structure of DNA / RNA molecules;

[0046] (5) The inhibitory e...

Embodiment 2

[0054] Example 2 Letermovir anti-SARS-CoV-2 activity effect in vitro

[0055] 1. Biosafety requirements

[0056] The in vitro anti-SARS-CoV-2 activity evaluation experiment of Letermovir involves virus culture. According to the requirements of the National Health and Medical Commission's "Biosafety Guidelines for Novel Coronavirus Laboratories (Second Edition)", all virus cultures are conducted at Biosafety Level 3 (BSL- 3) In the laboratory. Use virus culture to extract nucleic acid, and the addition of lysing agent or inactivating agent is carried out under the same level of laboratory and protective conditions as virus culture. Nucleic acid detection and other operations after the live virus is inactivated by a reliable method are carried out in a biosafety level two laboratory (BSL-2).

[0057] 2. Experimental environment

[0058] Room temperature: 22°C, relative humidity: 55%.

[0059] 3. Experimental method

[0060] 1. Experimental grouping

Abstract

The invention belongs to the technical field of medicines, and particularly relates to application of Letemovir in preparation of an SARS-CoV-2 novel coronavirus inhibitor. Research finds that the Letemovir can be combined with an RBD region, combined with an ACE-2 receptor, on a spike protein S1 of SARS-CoV-2 novel coronavirus to prevent the virus from entering cells, so that virus replication isinhibited. Therefore, the Letemovir can be used as an inhibitor of the SARS-CoV-2 novel coronavirus, a new thought is provided for preventing and / or treating the SARS-CoV-2 novel coronavirus, a theoretical basis is provided for development of clinical tests, and the Letemovir has important medical research value.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to the application of Letermovir in the preparation of SARS-CoV-2 novel coronavirus inhibitors. Background technique [0002] Highly pathogenic coronavirus infection has become a public health issue of widespread concern in this decade. Such as Severe Acute Respiratory Syndrome (SARS, 2002-2004), Middle East Respiratory Syndrome (MERS, 2012-present), SARS-CoV-2 (COVID-19), each of these diseases has brought serious consequences to human health and economic development. Huge shock. It has been reported that SARS-CoV-2 is a new member of the genus Betacoronavirus (Beta-CoV), which is closely related to severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV) and several bat coronaviruses. [0003] Since there are no targeted effective drugs and vaccines, the development of new drugs for SARS-CoV-2 is of great significance. In this war without gunpowder, many scientific resea...
